Abstract

The invention discloses a deep hole boring machine with high machining precision. The deep hole boring machine specifically comprises a boring machine base and a straight guide rail, the boring machine base is provided with a clamping device, the clamping device is arranged at one end of the top of the boring machine base and is fixedly connected with the boring machine base, and the top of the straight guide rail is provided with supporting devices and a drill rod penetrating through the supporting devices and connected with the supporting devices in a rotating mode. The bottom of each supporting device is in sliding connection with the straight guide rail, each supporting device comprises a fixed base, the bottom of each fixed base is clamped on the straight guide rail and is in sliding connection with the straight guide rail, and limiting grooves are formed in the top of each fixed base. The invention relates to the technical field of deep hole boring machines. By means of the deep hole boring machine with the high machining precision, the coaxiality between the drill rod and the supporting devices can be conveniently adjusted, adjusting operation is convenient, it can be avoided that large gaps are generated between limiting plates and the limiting grooves, it is avoided that the machining precision is affected by shaking of the drill rod, the qualified rate of workpieces can be increased, and cost is saved.

Description

technical field [0001] The invention relates to the technical field of deep hole boring machines, in particular to a deep hole boring machine with high processing precision. Background technique [0002] The deep hole drilling and boring machine is used to process deep holes with an aperture ratio of 1:6 or more, such as deep holes in parts such as gun barrels, gun barrels, and machine tool spindles. The deep hole drilling machine that rotates the workpiece (or the workpiece and the tool rotate at the same time) is similar to Horizontal lathes, deep hole drilling machines are general, special and modified from ordinary lathes. In order to facilitate cooling and chip removal, the layout of deep hole drilling machines is horizontal. The main parameter of deep hole drilling machines is the maximum drilling depth. However, the currently used horizontal deep hole boring machine drill rods are prone to eccentricity after long-term work, resulting in low precision of the processed ...
